The border style you are defining is only affecting the outer table border. And apparently a TR element does not have a border property. To define the border on the td elements, obviously you could put a class definition in each td elemtent, but I thought that would be redundant and should not be necessary. I was up against a wall until I found some info that led me to do something like this:
Instead of defining your .thickBorder class, you need to define the thickBorder td element. So, change your line

Code:

.thickBorder {

into

Code:

.thickBorder td {

It should work then. Notice that if you are using styles that do work for TR, you will probably want to leave them applied to the TR and not to TD elements, since, for example, background would leave space inbetween cells if there were any cellspacing. So then you would need two definitions, one for ".thickBorder" to be applied to TR, and one for ".thickBorder td" to be applied to TD.

Thanks for your reply. I thought to try assigning to TD but then I'd get a border between each cell as well. Oddly enough, though, I managed to get the TR border working on another page somehow, just not on this one. Guess I'm a sporadic genius.

You could always nest the entire row in another table, and put a border attribute on either the TD it was in or the new table itself... but I would think there should be a "cleaner" way to do it. Oh well.
